BENJAMIN P. HAMMERSTAD AND JOHAN LYKEN, OF OAYUGA, NORTH DAKOTA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 439,653, dated November 4, 1890.

Application filed July 24, 1890.

To aZZ whom it may concern.-

Be it known that we, BENJAMIN P. HAMMER- STAD and JOHAN LYKEN, citizens of the United States, residing at Cayuga, in the county of Sargent and State of North Dakota, have in- Vented. certain new and useful Improvements in Oar-Couplings; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The special object of the invention is to make an automatic car-coupler which may be conveniently uncoupled without danger to the operator.

The invention will Iirst be described in connection with the drawings, and then clearly pointed out in the claims.

Figure l of the drawings is a side view showing the parts of coupling together; Fig. 2 a front View, and Fig. 3 a sectional view, of the draw-head.

In the drawings, A represents the drawhead and B the draw-bar, the latter movable between guides ct d and against a bumperspring in the chamber a. The bottom of the draw-bar B is slotted at b to receive the hook C, which is pivoted at the end of its shank on the bolt c', which slides in the slots b b when the draw-bar is moved. The hook C is also provided with a longitudinal slot c2, through which passes the cross-bar d, which connects the perpendicular parallel bars d d. The latter slide up and down in the guides E E, and. are provided with the side arm d2. This arm is lifted by means of the shoe f at the lower end 'of a lift-bar F, which passes through the guides G H. On the upper end of the lift-bar F is formed the rack f', which is worked by the cogs Za on the end of the hand-lever K.

L is a weighted catch which holds down the Serial No. 35 9,774. (No model.)

lever K, and thus holds up the hook C, the weight Z holding the catch Z over the lever.

Z2 is a foot-piece, on which the operator bears in order to hold the catch back while the lever K is brought down.

To one side of the slide D is attached a lever M, which lifts the arm d2, so as to uncouple from one side of the car. This lever works in a keeper N, which has holes n, through which may pass the pin O, so as to hold up the hook C, and turns in bearings on the bottom of the car.

By the means described the coupling is manipulated with lthe greatest ease and convenience.

Having th us described all that is necessary to afull understanding of ourinvention, what we claim as new, and desire to protect by Letters Patent, is-

l. The combination, with the draw-head A, carrying a bumper-spring, and the slotted draw-bar B, of the slotted hook O, pivoted on a slide-bolt c', the slide D, having the crossbar CZ, side bars CZ cZ, and side arms d2, the guides E E, the lift-bar F, having rack f at .the upper end, and the lever K, having the end cogs Zt, whereby the hook C may be uncoupled, as described.

2. The combination, with the lift-bar F and lever K, connected by rack and pinion,of the catch L, having the weight Z at one end, the foot-piece Z2 at lthe other, and the intermediate hook Z over the fulcrum, whereby the slide D and hook O may be held up, as described.

In testimony whereof we affix our signatures in presence of two witnesses.
